Since all of this part of the STL runs at compile-time, arduino being an embedded platform is not a good reason to exclude it.

In particular, things like std::remove_reference are needed to implement #5875

Why you say it's excluded? AFAIK the build of the toolchain did not exclude anything, maybe those are not implemented yet for AVR?

You're right, this is really a complaint against avr, not against arduino - so it wouldn't be unreasonable to close this as out of scope.

It might be nice if arduino could provide it to make up for its absence from avr though

Ok the question is then, where we can find a good implementation of them? I think that Arduino doesn't have enough resources to maintain his own implementation of the standard C++ lib.

uclibc++ has a decent implementation (also available in a few Arduino libraries), though it is incomplete (especially most of C++11 is missing). Not sure if type_traits is among it.
